Aug 27, 2010

I need to open and read a Dbase file in my ASP.NET application. When I try to open the connection, I am getting the exception "Could not find installable ISAM."

Dim connection As OleDbConnection = New OleDbConnection(connectionString)

Could Not Find Installable ISAM

Nov 14, 2011

I'm using vb.net 2003 and I want to read excel file 2003 using OleDb Connection. But I have a problem when I'm putting the IMEX=1 property on the connection String. But when I have to romove this IMEX property, the system run without an error. Here is my connection string

xlsCon = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & pathName & " ; Extended Properties=Excel 8.0;IMEX=1")

I need to put IMEX property so that it tells the driver to always read intermixed (string, integer, date) data type on each cell.

Here is the error I've encountered.

Error "Exception Of Type 'System.OutOfMemoryException' Was Thrown." When Try To Read 100MB File

May 4, 2012

i want to ask about read file and then convert to binary i am using this code

Function readd(ByVal path As String, Optional ByVal Separator As String = " ")
' Store the line in this String.
Dim line As String

[code].....

it works fine to read small file, example 2MB file, etc but it get error "Exception of type 'System.OutOfMemoryException' was thrown." when try to read 100MB file i think the error code because the file is too big

For Each Character As Byte In ASCIIEncoding.ASCII.GetBytes(line)
oReturn.Append(Convert.ToString(Character, 2).PadLeft(8, "0"))
oReturn.Append(Separator)
Next

how can i read 100MB or bigger file?or maybe is it another method / code to read a file and convert it into binary?

Reading DBase DBF With Non-English Characters

Mar 15, 2011

I have a tool which reads dBase files and uploads the contents to SQL Server, part of a system to import shapefiles. It works but now we have a requirement to import files that include non-English characters (Norwegian in this case, could be other languages later) and they're being corrupted. The dBase files are being read using an OleDbDataAdapter. Stepping through the code I can see that the text is wrong as it is read in. I'm assuming it's something to do with code pages or Unicode but I have no idea how to fix it.A dBase Reader application tells me the DBFs are in code page 1252 - I don't know if this is correct. My upload tool runs on Win7 with English (UK) regional settings.[code]Is there a way to tell OleDbDataAdapter what code page to use or a better way to read dBase files from VB.Net?

DB/Reporting - Updating DBASE IV Databases In .NET

Sep 7, 2010

I am attempting to modify DBaseIV files using ADO in .NET I am able to open and read the data with no problem but everything is showing as read only and there is no way (at least that I can find) to perform Updates/Inserts/Deletes to the underlying Database table.

There seems to be almost no documentation that I have been able to find dealing with DBASE files. I have found a few references that BDE (Bordland Database Engine) needs to be installed and used for changing DBASE database files. However, it appears that BDE must be purchased. I found one reference that indicated ADO Jet 3.5 would work but 4.0 would not. Then I found another that said 4.0 had been updated to include Update/Insert/delete SQL interfaces.

Can anyone point me in the right direction for being able to modify a DBASE IV database table using ADO (or some other method within .NET) It is currently not possible to change from DBASE to another database structure this may be coming in the next year or so but will still need to perform modification to DBASE files for the forseable future.

I'm unsure on how to set up a connection in my application to connect with a dBase IV database that uses indexes (not sure if it matters if it has indexes or not). I will need to both read and write to this database.
